Musical Ruler

The Musical Ruler is a plastic ruler with printed finger markings and note positions. Sliding the ruler up towards the edge of the desk alters the note, enabling you to play anything from Abba to ZZ top.

Also, we've tried it, and you just cannot draw a straight line with a tuba. In fact this may be the only product in the world that you can draw straight lines with in your diary and then use to play "House of the Rising Sun" on the edge of your desk. Pack contains one musical ruler and one guide to ruler playing!
